置を規制するようになつている。 Further, a pair of upper and lower punches 9 and 10 are provided at the upper and lower sides of the gear case 3 to pressurize the upper and lower surfaces of the gear case 3 and cause plastic flow. Punch portions 9a, 10a and regulating surfaces 9b, 10b serving as positioning means for gear case 3 are integrally formed. The regulating surfaces 9b and 10b are punches 9 and 10.
Gear case 3
The upper and lower surfaces of the gear case 3 are brought into contact with each other, and the position of the gear case 3 in the vertical direction is restricted.
下側パンチ１０のパンチ部１０ａの加圧面積
は、上側パンチ９のパンチ部９ａよりもギヤケー
ス３に優先的に圧入されるように小さく設定され
ている。 The pressing area of the punch portion 10a of the lower punch 10 is set to be smaller than that of the punch portion 9a of the upper punch 9 so that the punch portion 10a is preferentially press-fitted into the gear case 3.

つている。 Further, the volumes of the upper and lower circumferential grooves 7 and 8 are set to be different depending on the size of the pressurizing area of both punches 9 and 10. That is, the lower circumferential groove 8
The volume of the upper circumferential groove 7 is smaller than that of the upper circumferential groove 7.
そして、上述したリングギヤ２のギヤケース３

ス３の接合面１１近傍に圧入され（第３図参照）、
それによつて塑性流動が引き起こされ、塑性流動
結合される。 Then, the gear case 3 of the ring gear 2 mentioned above
After external fitting, the upper and lower punches 9 and 10 are press-fitted into the vicinity of the joint surface 11 of the gear case 3 (see Fig. 3),
Plastic flow is thereby induced and plastic flow coupling occurs.

対位置が規制面９ｂ，１０ｂにて常に一定に保た
れるため、リングギヤ２とギヤケース３との相対
的な位置ずれが防止できる。 During plastic flow coupling, the upper and lower punches 9, 1
0 displaces up and down at the same time, but the speed at which the punch is pressed into the member is lower than that of the punch portion 10a, which has a small pressurizing area.
Since this is faster, the punch part 10a of the lower punch 10 is press-fitted into the gear case 3 preferentially than the punch part 9a of the upper punch 9, and the lower punch 10
The plastic flow coupling of the portion near the punch portion 10a is performed using the upper punch 9 as a base, and after that, the gear case 3 is regulated by the regulating surface 10b of the lower punch 10, and then the pressurizing area of the upper punch 9 is Since the plastic flow coupling is performed in the part near the wide punch portion 9a, the relative position of the gear case 3, which is pressurized by the upper and lower punches 9 and 10, with respect to the ring gear 2 is always at the regulating surfaces 9b and 10b. Since it is kept constant, relative positional deviation between the ring gear 2 and the gear case 3 can be prevented.
また、周回溝７，８が容積が上下側パンチ９，

は起らず、変形は生じない。 Further, the volumes of the circumferential grooves 7 and 8 are the upper and lower punches 9,
10, plastic flow occurs almost uniformly in the upper and lower parts of the gear case 3.
Therefore, the upper punch 9 is press-fitted and the regulating surface 9
Even if b comes into contact with the upper surface of gear case 3, no relative vertical displacement occurs between ring gear 2 and gear case 3, and no deformation occurs.

上に加圧することがない。 Furthermore, by providing the regulating surfaces 9b and 10b, the magnitude relationship of the pressurizing area of the upper and lower punches 9 and 10 to the gear case 3 can be easily switched during the pressurizing process (i.e., the pressure applied by the lower punch 10 initially). (The pressure area is small, and after the regulating surface 10b makes contact, the pressure area by the lower punch 10 becomes large), and the plastic flow of the gear case 3 can be performed on the upper and lower sides one by one, and the upper and lower punches 9 and 10 are not pressurized more than necessary.

It can be seen that when the ratio S of W 3 (=W 4 /W 3 ) is approximately 0.9, the amount of warpage x of the ring gear 2 becomes 0.
